Y Plus Calculation

• Y Plus calculation is important to correct wall heat fluxes for momentum and heat transfer
• CFD engineers should check  Y plus to decide first element adjacent to wall in such a way that, y+ < 1

•   The Y-plus calculation is given, you can enter your values in the column of input values
